Let me know what you find out. I will watch this thread with interest!

I spoke to MR Automotive - they quoted the HD part that they stocked as RTC 4235 (like everybody else...) and they then recommended a business in Brisbane which makes shocks. I am yet to work out why the RTC 4235 items I had in my hands several months ago most definitely did not extend long enough to fit to my vehicle. I know that it is sitting a little high at the moment - but that is immaterial: The extended length quoted for rear shocks on 88s is 20.28". The RTC 4235s I had fell almost four inches short of that. What the hell is going on? It can't be this hard to get a HD shock for an 88's rear.

Are you sure that the RTC4235 shocks you have are ACTUALLY RTC4235 shocks and not another part number sent in error badged as RTC4235?

Hi John
I checked the old shocks I have a here (a HD set off the front of a 109 and a set off the rear of an 88) and neither set extends anywhere near the 20.88 inches. One set are Pedders so no point contacting them!
Keep searching!!

Have you got Parabolics? if so I would recommend getting a set off a coil sprung vehicle,like a RRC or Disco 1,I have just replaced mine on the D1 got them from REPCO, Maxtrax brand, gas about $175 a set :) They should be able to do a set of "eye-eye" types as my coil sprung vehicles and the LWB 2a are "eye-pin" type if not give them your specifications open -closed double action and see what they come up with :)


cheers

Good point. I assume that they were. It is a bit late to check now, as I returned them to the supplier.

Thanks,

John

Nope, they're standard springs. Thanks for the info on the Maxtrax shocks. I think what I will do next will be to phone somebody who carries the RTC 4235 shock and get them to pull out a set and check them for travel. maybe there was something amiss with the ones I which were delivered to me.

Thanks,

John

John, my 88 sits fairly high and I measured the rear shocks at rest at a shade under 20", so must be much more extended, front shocks were 16" at rest. The 20" extended sound more like front shocks??

Thanks for that. That sounds more or less like my 88's rear. It sits at about 21" now, but I know that the car will be settling lower (but not a hell of a lot lower) once it gets back on the road. No way is it going to drop four inches, anyway, to get down to the maximum length of the shocks I bought.

What you describe certainly sounds like more like the ticket. It seems to match up better with the quoted specs, anyway. What sort are they? Are they standard rated or heavy duty?

I went out this morning and measured the rear shock length for Bill.
middle of bolt to middle of bolt (eye to eye) was 18.5". And I know Bill sits about 1" higher than stock at the rear due to some heinous cart springs that are under there currently.

I couldn't see what the rear shock manu was due to years of grime/faded paint/overspray but the fronts are Gabriel, so I popped on to their website and found they still list a HD Gas Ultra Shock G63510 for the rear of a SWB

The application chart is weirdly under NewProducts.

Might be worth giving them a ring to see what the lengths are of that option.

Thanks for that. I'll chase that one up too. It's interesting to see that measurement from Bill, because, even though it is not as large as that for my Landy, is still longer than the maximum extension of the RTC 4235 shocks I was sent.

Cheers,

John
